OBJECTIVE: Neutropenia is frequent during treatment of chronic hepatitis C (CHC) with peginterferon and ribavirin. It remains unclear whether neutropenia is associated with infection in CHC. The aim was to study the relationship between neutropenia and infection during treatment with peginterferon and ribavirin for CHC.

METHODS: A retrospective cohort on 399 patients treated with peginterferon α and ribavirin derived from our hospital database was conducted. The occurrence of infections and their relationship to neutropenia were investigated. Potential risk factors for infection were identified by multivariate analysis.

CONCLUSION: Infections during treatment with peginterferon α and ribavirin for CHC are not associated with neutropenia. The independent factors associated with infection are age, diabetes, and cirrhosis.
